Coal

In ore smelting, the coke as the reducing agent has an important influence on the cost-effectiveness of the process and the quality of the final product.

The quality of the coke depends on the mixture of different coal qualities used, the measurement of actual coal use in the coking plant and optimum classification with screening machines.

In the coal mixing plant, weighfeeders or discharge feeders remove different types of coal from the bunkers to form the mixture in accordance with a specified recipe.

Coal

Correct filling of the coke-oven batteries depends on the load cells that weigh the bunkers on the vehicle or weighing tracks in its path. These ensure a high level of accuracy and complete balancing, thus making sure that materials are used economically.

Schenck Process vibration technology is used in the classification process that follows to precisely sort the coke into the required particle sizes. The equipment must be extremely resistant to wear and corrosion. Schenck Process linear vibrating screens have been delivering a high standard of performance for decades, making optimum use of fuel for the blast furnace.

High-efficiency weighing and feeding technology for all relevant process stages

The global consolidation of the steel industry demands optimised processes. Weighing and feeding systems have always played an important part in economical and safe steel production: from the mass control and feeding of raw materials to the processing of pig iron and crude steel to the sale of the finished products.

The weighing and feeding systems used for internal control in the production area (scrap yard, blast furnace, converter, EAF and continuous casting machine) have to operate in a particularly harsh environment. They handle weights of 1 to 1000 tonnes, sometimes at extreme temperatures.

FEEDING FEEDING

Weighing and feeding technologyMaximum precision in bulk material handling

Weighing, feeding and conveying equipment handles a range of bulk materials from the finest to the toughest with very high accuracy. The harsher the environment, the more robust the technical systems need to be.

Schenck Process weighing modules, for example, calculate the highly precise addition of alloying agents in electric steelworks or the exact weight of a ladle weighing several tonnes in a continuous casting plant. Intelligent weighing and feeding systems allow direct feeding and precise measurement. All logistics are handled by loading and automation systems. Our weighing, feeding and conveying systems measure weight, force and material throughput. They offer robustness, precision and reliability – and are built to withstand the harshest conditions.
